This invention relates to sump and bilge pumps and has for its object, a pump unit which is particularly simple, compact and of light weight in construction and highly efficient and durable in use and has a particularly simple and efficient means for supporting the pump unit in any of the situations in which such pumps are used.

The invention consists -in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In Vdescribing this invention, reference is had tothe accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a vertical sectional view of this bilge pump, two of the positions of the supporting means being shown in dotted lines.

Figure 2 is a fragmentary elevation of the lower. part of the pump shown in Figure 1, showing the position of the float and switch operated thereby at the beginning of Athe pumping operation.

Figure 3 is a detail fragmentary elevation of the float operated switch, mechanism looking to the right in Figure 1.

Figure '4 is an elevation of the-detached cap of the body.

Figure 5 is a plan view of the pump easing.

Figure 6 is an elevation of the pump showin one of the applications thereof to a sump formed by a tile. A

Figure 7 is a fragmentary plan view of parts seen in Figure 6.

Figures 8 and 9 are views similar to Figures 6 and 7 showing the pump as supported in another manner.

:Figures 10 and 11 are perspective elevations and plan views of the pump supported on a float, the float being shown in sections in Figure 10.

This pump comprises generally, a base, av pump casing mounted on the base, a body, an electric motor carried in vertical position within the body and having itsA shaft extending into the pump casing, an impeller mounted on the lower end of the shaft iu the casing,l a perforated cylindrical Wall inter-l posed between the base and the body, float y operated switch mechanism depending from 192s. serial No. 267,211.

the body within the perforated Wall, the body having a plurality of means for supporting t-he pump in different situations. v

1 designates the base Which maybe of any suitable form, size and construction, it being formed with a cylindrical boss or proj ection 2 having a flat top.

3 is a pump casing mounted on the top of the base and the base closing the lower side of the pump casing.

and has a plurality of sets of means on its outer side for receiving members for supporting it. The body is here shown'as formed with an external flange 10 formed with dow-nwardly and outwardly inclined sockets 11 for receiving the upper ends of legs 12 which support, tripod fashion, the body on the bottom of the sump.

The body is also provided with radially eX- tending sockets 13 for supporting the members 12 in `horizontall position as shown in Figures 8 and 9. The body is provided with a suitable cap 14 secured thereto as by screws 15, this cap enclosing terminals of the motor to which the wires W are connected and also a suitable Ventilating fan 16 mounted on the upper end of the motor shaft. The cover 14 :is provided with a handle 14:a on vthe top side thereof.

17 is a cylindrical perforated wall secured at its upper end as by screws 18 to the body 1 beneath the flange 10 and at its lower end to the base as by screws 20.

22 is the shaft of the motor or an extension thereof which extends down through the cylindrical wall 17 and through an opening 23 in the top of the pump housing 3.

24 is an impeller mounted on the lower end of the shaft within the housing.

aoy

lou y This Shaft 22 has its bearings in the, body 1 and none in the pump casing.

to the motor is closed through .fthef mercury switch 2,6 and when the float moves into the.' pbsition shown in Figure 1, the circuit thou h the motor is open.

Int, igure 6, the arms 12 are shown as arranged in tripod fashion on the bottom of a sump formed by a tile 31. l

In Figure 8, the pump is shown as supported in a similar sump by the arms12 arranged in horizontal position so that their ends rest on the top of the wall of the sump or tile or on the bottom of thejbell usually formed at one endotl the tile.-

In Figures 10 and 11, the body is shown as supported -by means o its Ila'nge 10on a iloat by means of screws extending through the llange into .the "heat, this loatbeing formed in two sections 3 2 and'33 with a cylinvdric'al hole formed between the Vselio'ns for' receiving the pump body with .the, ange'10. overlying the upper face of said parts 32,` 33. Owing 'to the 'cylindrical costruction of the pump unit, it is articularly smallr and compact and relative .light-so,that it-cam be easily carried and a so'owing tojsuchfcon-f struction, it can be 'readily applied to .vlariousy forms of sumps-or other receptacles-fromwhichlwater is to be pumped or to -a .float for. the purpose ofy 'supplying'4 watert from a stream, large reservoir or4 other body of water.

What I claim is; A A 1. A sump pump .comprising a base, a pump casingfmounted on the base and having an outlet, a body, an lelectric motor mounted in the body :and arranged in vertical position, the motor yshaft extending into the pump housing and an im eller mounted f on the,

'lower end of the sha t within the pump cas-p ing, the casing Vhaving an'finlet and a perorated wall 'secured at its upper end to the body and at its lower end .tothe base, thel body having two sets of sockets arranged at dill'erent angles for receiving. supporting. arms, one set being arranged substantially radially wherebythe arms extend horizontally and the pther set being downwardly to serve as standards. p I 2. A' sump pumpcomprisinga base, a pump casing -mounted on` the base and hav-` mentira' spaced apart. from the base, an electric motor mounted in the body 'and arranged in vertical' position, the motor shaft extending vertically into the pump'casing', an impeller mounted on the lower end of the shaft within the pump' casing, the pump casinghaving' an inletaround the shaft,and a perforated enclosing wall between the base and the body and secured at its upperand lower ends respectively to the body and the base, a switch for controlling'theactuation ofthe motor -and float means withinthe cylindrical wall for controlling the operation of the switch. -In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of (')nondaga,'and State of New lYork, 'this 27th day' of March, 1928.
